Overview

MR spectroscopy measures tissue metabolites to provide biochemical information non invasively. It complements structural MRI in brain tumor infection and metabolic disorders. Interpretation requires expertise and standardized acquisition.

Clinical Applications

Spectroscopy aids in tumor grading and differentiation from treatment effects. It can detect metabolic abnormalities in epilepsy and metabolic disease. Combined with other MRI sequences it enhances diagnostic confidence.

Technical Considerations

Voxel placement shimming and spectral resolution affect data quality. Quantitative analysis and reference ranges support interpretation. Quality control and training improve reproducibility.

Research Directions

Advanced spectroscopy techniques explore novel metabolites and higher field strengths. Integration with multimodal imaging supports translational research. Standardization efforts aim to broaden clinical adoption.

Overview

MRS measures biochemical compounds such as NAA choline and creatine to provide metabolic information complementary to structural MRI.

Technique

Single voxel or multivoxel spectroscopy requires careful voxel placement and shimming for reliable spectra.

Clinical Uses

Brain tumor characterization metabolic disorders and liver or prostate metabolic assessment.

Limitations and Safety

Lower spatial resolution and susceptibility to contamination from adjacent tissues. Interpretation requires expertise.
